{"data":[{"source":"bio.acousti.ca","id":"58327","topic":"behaviour","value":"The calling song of P. galvagnii consists of an echeme, lasting 1\u20136 s, repeated more or less regu- larly with intervals of about 1\u20133 s (fig. 36). An echeme usually consists of a series of 4\u20138 microsyllables, followed by a series of 30\u2013150 macrosyllables. Only very rarely echemes can be heard that consist of only microsyllables or echemes ending with microsyllables.\n\nMicrosyllables last only 1\u20133 ms and are repeated at the rate of about 25\u201332\/s. Macrosyllables last about 60\u201375 s and are repeated at the rate of about 10\u201313\/s. Oscillographic analysis shows that only an unidirectional (presumably closing) movement produces sound.","topic_link":"http:\/\/rs.tdwg.org\/ontology\/voc\/SPMInfoItems#Behaviour","info_url":"https:\/\/bio.acousti.ca\/node\/58327"}]}
